Diagnosis and Management of Bullous Disease

Bullous diseases are a group of dermatoses primarily characterized by the presence of vesicles (0.1-0.9 cm) or bullae (>1 cm). There are various categories of bullous disease: allergic, autoimmune, infectious, mechanical, and metabolic. These diseases affect individuals in all decades of life, but older adults, age 65 and older, are particularly susceptible to bullous diseases of all etiologies. The incidence of these disorders is expected to increase given the advancing age of the general population. In this comprehensive review, we will outline the common bullous diseases affecting older individuals and provide an approach to evaluation and management.
